Yes. It might sound counter-intuitive or even ironical but the next logical step is to make the type system more, not less expressive and to add completely dependent types. Every language already has them to the extent of Array<T, N> (or T[] & { length: N }, or a recursively defined Tuple<T, N>), but having true flow- and value-dependent types would allow for more concise and expressive code.
